 ** Installation
 
-You will need a Raspberry Pi that is attached to your network. I am using a Raspberry Pi Model A+ due to its really adorable formfactor and the fact that I have some WiFi dongles laying about.
+You will need a Raspberry Pi that is attached to your network. I am using a Raspberry Pi Model A+
+due to its really adorable formfactor and the fact that I have some WiFi dongles laying about.
 
-First off, get the =rpi_ws281x= library working, and verify that =strandtest.py= works for you. I followed [[https://learn.adafruit.com/neopixels-on-raspberry-pi/][this Adafruit tutorial]] to get it working, I would recommend the same; you will need a 3v3->5v logic level converter, which is unfortunate, but it makes this so much easier.
+This is based on the =rpi_ws281x= library, and I ship an [[http://ansible.com][ansible]] playbook to provision it.
 
-Once you have that working and installed, install the =matrix-client= from Pip.
+Remove the =rrix.setup-home= role from =playbook.yaml= and run:
 
 #+BEGIN_SRC sh
-sudo pip install matrix-client pyyaml pytz
+ansible-playbook -i ../devops/hosts playbook.yaml --become
 #+END_SRC
 
-Yes, I install it in to the main Python library path, because I'm an infoterrorist. It's an embedded Raspberry Pi, deal with it.

 ** Usage
 
+As root: (due to the DMA requirements)
 - Create a =~/.mcatrc=
-- Run =python ./lightrix.py --room "<YOUR ROOM ID>" -c ~/.mcatrc= and it'll fire up
-- Go in to the room and type "rainbow"
+- Run =python ./lightrix.py -r "<YOUR ROOM ID>" -c ~/.mcatrc= and it'll fire up
+- Go in to the room in Vector or so and type "rainbow"
+
+The playbook will install a systemd unit file =lightrix.service= which you can start and enable to
+your heart's content
+
+*** Remote
+
+There is also now a remote control included which you can run to allow you to control the lights
+from a web-page.
+
+- Create a =secrets.js= which defines the following variables, and put it in =remote/=
+  - =accessToken=: A valid access token which the webpage will use to make requests to the HS as
+  - =hs=: A fully-qualified homeserver URL
+  - =uid=: the UID that the =accessToken= represents.
+  - =rooms=: an array of Room IDs which you can use to toggle to mutliple lightrix installations
+    (assuming each one runs in its own room)
+- run =python -m SimpleHTTPServer= in the =remote/= directory
+- browse to =http://DOMAIN:8000= to view the remote
